• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty xang) OR (((ty hang) OR (thi hang)))) cho hoc. hieu ve cac duc van anh vai cua cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty xang) or (((ty hang) OR (thi hang)))) cho hoc. hieu ve cac duc van anh vai cua cau~".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty xang) or (((ty hang) OR (thi hang)))) cho hoc. hieu ve cac duc van anh vai cua cau*.
